MACHINE FOR CLEANING BOTTLES.

SPECIFICATION forming part of Letters Patent No. 714,739, dated December 2, 1902. Application filed November 25, 1901. Serial No. 83,507. (No model) T0 a/ZZ whom, it may concern:

Be it known that I, ANDERS ANDERsnN PINDSTOFTE, manufacturer, of Copenhagen, in the Kingdom of Denmark, have invented certain new and useful Improvements in Machines for Cleaning Bottles, (for which l have applied for patents in Denmark on the 25th ofApril, 1901, No. 538/01; in Norway on the 30th of April, 1901, No. 13,821; in Sweden on the 30th of April, 1901, No. 806/01, and in Germany on the 7th of May, 1901, No. 12,540) of which the following is a specification.

This invention relates to a machine for cleaning bottles and comprising two rotary brushes mounted side by side upon the same frame and two frames each of which is adapted to be displaced relatively to one of the said brushes. These frames support the bottles to be cleaned and also a guide-cone which bears against the mouth of the bottle and prevents this latter from damaging the rotating brushes. ances are so arranged that the frames alternately bring the bottles against the brushes and that the guide-cone is pressed against the mouth of the bottle in the operative position, while when the frame is drawn back this cone is slightly removed from the mouth of the bottle, so as to permitthis latter to be withdrawn from the frame and replaced by a fresh one.

The invention is illustrated in the accompanying drawings, in which- Figure 1 is a plan view of the apparatus. Fig. 2 is a longitudinal section through the same, and Figs. 3 and 4 are diagrammatic views of a tension device.

The two similarcleaning devices are ar ranged side by side upon a common frame a. Each of them consists of a rotary brush b, a

\ frame d, displaceable relatively to the brush along guide-rods c c, the bottle to be cleaned being placed in the frame. In front of each frame is displaceably arranged, also upon the guide-rods c c, a guide-cone e, which in the operative position bears against the mouth of the bottle and prevents any injury to the brushes from this latter. These parts may be of any convenient construction, and those of known machines may be adopted. Beneath each extremity of the frame a are arranged two horizontal grooved pulleys or These` two similar cleaning applif chain-wheels f g of equal diameter, an endless cord or chain passing over them.. Each of the lengths 7L t' of the driving cord or chain is attached to one of the two frames d in such a manner that one frame is invariably carried forward while the other is drawn back. Upon that horizontal side of the pulley g, prefer ably at the point at which the length of cord h makes a tangent with the pulley g when the frame attached to this length of cord h remains at rest, a cord .7c is fastened, this cord passing over a roller Z and having attached to it a counterweight m. Each of the guidecones is provided with a rearwardly-directed handle 'n and also with a cord o, each of these cords being carried between a pair of rollers the right-hand frame, together with the bottle-contained in it, is pressed against the brush b as the cord 7c, which now occupies the position shown in Fig. 3, and with it the length of cord fi, to which the right-hand `frame is attached, is placed in tension by the counterweight m. At the same time the guide-cone e of the right-hand carriage is tightly pressed against the mouth of the bottle by means of the counterweight t, owing to the fact that the cord o between this weight t and the guide-cone e now passes over the rollers and tends to pull the cone back-that is to say, against the bottle. Upon the other hand, the other guide-cone is so far removed from the left-hand frame, owing to the fact that its cord o now passes over the roller r and tends to move the cone forward, that the bottle contained in this frame may be readily removed therefrom and replaced by a fresh bottle. When the bottle in the right- 4hand frame has been cleaned, it is carried back by acting on the handle fn, of the right guidecone, whereby the guide-cone is caused to recede, carrying with it the frame di. During this operation the pulleys g and f have been rotated in the direction of the arrow, Fig. 3, so that the left-hand frame d and its guide-cone have been drawn forward.

ICO

The cord 7c now assumes the position shown in Fig. 4, in which the left-hand frame is pressed against the brush. At the same time the counterweight t of the left-hand guidecone, the cord o of which now passes over the roller s, presses the guide-cone against the mouth of the bottle, while the counterweight t of the right-hand guide-cone, the cord o of Which now passes over the roller r, removes the guide-cone from the cleaned bottle in the right-hand frame, so that the latter mayhbe readily removed and replaced by a fresh bottle. When the bottle in the left-hand frame has been cleaned, it is drawn back by acting upon the handle n of the left-hand guidecone in the manner already described, whereby'the grooved pulleys g and f are caused to rotate in the direction indicated by the arrow in Fig. 4, the parts resuming the position first described, as shown in Fig. 3. These operations are continued, the bottles being placed alternately in and removed from the oppositely-displaced frames.

The grooved pulleys may of course be arranged vertically, if desired.

On the dra-wings the frames d are shown displaceable along guide-rods; but of course the frames can also slide on wheels instead of along guide-rods.

What I claim, and desire to secure by Letters Patent of the United States, is-

1. In apparatus of the character described, the combination of reversely-actuated bottlecarrying frames or carriages, and a common means for simultan eously eecting such actuation, substantially as set forth.

2. In apparatus of the character described, the'combination of reversely-actuated bottlecarrying frames or carriages, means for simultaneously effecting such actuation, means for guarding the neck ends of the bottles, and means for automatically reversing the movement of said guarding means as said carriages are moved rearwardly, substantially as set forth.

3. In apparatus of the character described,

the combination of reversely-actuated bottlecarrying frames or carriages, oppositev end wheels, with an encompassing endless belt connected up with said frames or carriages, and means for effecting such reverse actuation of said frames or carriages, substantially as set forth.

4. In apparatus of the character described, the combination of a bottle-carrying frame or carriage, and means for guarding the neck ends of the bottle, adapted to engage the forward end of said frame or carriage, and to provide for manually effecting the rearward movement of said frame or carriage, substantially as set forth.

5. In apparatus of the character described, the combination of reversely-actuated bottlecarrying frames or carriages, means for effecting simultaneously such actuation, and means adapted to engage the forward ends of said frames, comprising bails or handles, and cones, the latter being adapted to engage the neck ends of the bottles, carried by said frames or carriages, said handles or bails being adapted to be manually actuated for effecting the rearward movement of said frames or carriages, substantially as set forth.

6. In apparatus of the character described, the combination of re versely-actuated bottlecarrying frames or carriages, opposite end wheels, with an encompassing endless belt connected up wit-h said frames or carriages, means for guarding the neck ends of the bottles, weighted means connected up With said belt and with said guarding means, for eecting the automatic return movement of the last-named, when said carriages have been moved to their rearward position, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.
